One of the only lightweight op-rod driven AR's I have felt is LMT's offering, which I handled quite a bit at SHOT in 2008 or 2010. I saw another company that was using a valve with a tiny valve spring in an op-rod, which is probably the worst idea ever. Imagine a little valve spring right near the gas block, that will see temps up to 500 degrees F...:confused:
If I remember right, that was Osprey Defense, who also claim a 10,000 round MBTF (Mean Time between Failure). They have been known to rig tests to make their system look superior to a DI system, including water submersion with duct tape covering the suppressor opening, which would have the same results with a DI gun.
I recently handled some LWRC M6's, and they were really heavy compared to a similar profiled DI gun.
A friend of mine who has been selling his own op-rod system just made a drop-in DI conversion for it, which I was joking about last week, tongue-in-cheek. I didn't think anyone would actually do it. He did do something that addresses another issue with the DI system's gas tube, which I am really interested in now. I'll have to check into it some more.
